CS4349
DAC ANALOG CHARACTERISTICS - AUTOMOTIVE (-DZZ)
Test conditions (unless otherwise specified): VLS = 1.35 V to 5.25 V, VLC = 3.14 V to 5.25 V, T_A = -40° C to 85° C,
input test signal is a 997 Hz sine wave; Valid with the recommended capacitor values on VFILT, VQ, and VBIAS and output
circuit as shown in the typical connection diagram in Figure 10and Figure 17; Fs = 48 kHz, 96 kHz, and 192 kHz; mea-
surement bandwidth 10 Hz to 20 kHz.
